Disclosed is a traffic counting model flowmeter. The traffic counting model flowmeter comprises two parts, i.e., a host computer and a USB interface circuit. The circuit of the host computer portion comprises a CPU, a FAT special-purpose chip, a perpetual calendar clock chip, an LCD and a keyboard circuit, wherein the CPU reads model flow metering information obtained by the keyboard circuit, the information, after being processed through the CPU, is displayed on the LCD in a certain format, at the same time, and the CPU controls the FAT special-purpose chip to write the obtained model flow information into an SD card according to an FAT file system format. The USB interface circuit transmits model flow data stored in the SD card to a PC under the control of the CPU.
